摘要：
A sufficient condition of applicability of the model of a chemical equilibrium mixture to gasdynamic calculations based on a comparison of the rate of change of the equilibrium concentrations of the products in gas-dynamic process with the rate of chemical reactions leading to the establishment of chemical equilibrium is obtained. An example of using this condition in examining the applicability of the model of a chemical equilibrium mixture to the products of detonation of spherical charges of oxyacetylene and hydrogen-air mixtures the in the air is presented.
